Bisphenol-A(BPA)
is a white, solid chemical produced by recombining
phenol and acetone catalyzed by hydrochloric
acid. BPA also referred to as 2,2-bis (p-hydroxyphenyl)
propane and Diphenyolpropane, has a structure
which makes it suitable as a monomer to produce
polycarbonate, epoxy, phenolic, polyester
and other resins. Used directly as am additive,
it improves the stability of many other resin
systems. The presence of two hydroxyl groups
at opposite ends of the BPA molecule permits
unhindered reaction with a variety of other
chemicals under reasonably mild process conditions
Health and safety information is available
through the appropriate Material Safety Data
Sheet(MSDS). |
